ROTARY MOTOR.

SPECIFICATION forming part of Letters Patent No. 350,196 dated October 5, 1886.

Application filed July 19, 1886.

To all whom, it may concern.-

Be it known that I, G. F. HERMANN HANKO, a subject of the Emperor of Germany, residing at Barmen, Prussia, Germany, have invented a new and useful Improvement in R0- tary Motors, of which the following is a specification.

This invention relates to rotary engines or motors; and its object is to makea motor which shall be simple in manufacture and effective in action.

In the accompanying drawings, in two sheets illustrating my improved motor, Figure 1 is a vertical cross section of the motor, taken through one of the steam-spaces, a or b. Fig. 2 is an end elevation of the motor, showing guide-groove and mechanism by which the slide-valve is operated; Figs. 3 and 4, plan views of the slide-box from above with cover removed, showing the slide-valve in its two positions. Fig. 5 is a central longitudinal section, and Fig. 6 a plan view,of the motor.

The motor consists of a cylindrical wheel or disk, t, keyed on the shaft s,and provided along its periphery with two grooves, a b, as shown in Fig. 5. This revolving disk, or, rather,the periphery of the same, is inclosed in the outer stationary fixed casing, g, which forms the fourth side of the steam-chambers a b, steamtight connection being obtained by the rings 7', of hemp or other suitable material.

Partitions z z are provided in the steamchambers a b, one in each, these partitions be ing arranged relatively to each other at opposite ends of a diameter of the disk. Each carries, as shown in Fig. 1, an inclined plane on that side of the partition facing in the direction in which the disk revolves. These planes reach from the upper edge of the partition to the floor of the steam-chamber, and serve to lift the flaps i, of which there are two, one arranged to fall in the steam-chamber a, and the other in the same manner in I). These flaps are hinged to the stationary casing between the inletport e and outlet n. The slide-box 7c is situated as shown in the drawings, and contains the slide-valve f, which alternately covers thesteam-inlet ports 6 e, motion being communicated to it for that purpose through the Serial No. 208,388. (No model.)

rod 0 and the balance-lever h, pivoted at its center in ajournal, Z, fixed to the casingg and carrying at the extremity of its lower arm a pin, which is guided between the flanges m on the edge of the periphery of the disk, and shaped as shown in Fig. 2. The partition 2 being situatedjust in front of the inlet-port c, the steam enters the chamber a through the port 6 and drives forward the partition 2, which acts as a piston and so turns the disk until the port eis closed by the slide-valvef, and the port 6 at the same time opened, which will occur at the end of half arevolution of the disk. The partition zis now situated a little in front of port 0'. The steam now enters the chamber b at port 6' and drives the partition 2 forward for half a revolution of the disk, the steam in a meanwhile acting by expansion until the partition 2 passes the outlet-port it, when the steam in the chamber a escapes. The partition, passing forward, lifts the flap i and arrives in front of the inlet-port e, in order to again be propelled forward by the steam,which now again enters at e.

The device for controlling the slide-valve consists of the groove formed between the two flanges m. These flanges are so arranged on the side of the disk as to form two semicircles placed end to end, one of larger radius than the other, the points oftrausition being rounded off, so that the movement of the lever h is not made too abrupt.

What I claim is In a rotary motor, the combination of two parallel steam-chambers, a and b, in the circumference of a disk, 15, within a casing, 9, said chambers being provided with the dividingwalls 2 z and with flaps t, hinged to the casing, with aslide-box, k, controlling-lever h, and groove m, substantially as described and illustrated.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

C. F. HERMANN HANKO.
